|Abstract: ||We have found strong visible photoluminescence (PL) from 0.4 nm carbon nanotubes embedded in the ordered channels of zeolite crystal matrix. The PL exhibits a broad emission band with an efficiency of ~1-5%. Strong polarization dependence is observed both on the excitation and emission, indicating a preferential optical dipole along the axis of carbon nanotubes. By correlating with the absorption and Raman spectra, we identify (3,3) and (4,2) tubes to be responsible for the PL peaks at ~2.6 eV and ~1.7 eV, respectively.|
